Microtrap for hybrid Rb-Yb+ systems — •Abasalt Bahrami1, Matthias Müller1, Jannis Joger2, Rene Gerritsma2, and Ferdinand Schmidt-Kaler11QUANTUM, Institut für Physik, Universität Mainz, Staudingerweg 7, 55128 Mainz — 2Institute of Physics, Universiteit van Amsterdam

Trapped ions represent a highly controllable quantum system with strong long-range repulsive Coulomb interactions [1]. Laser cooled ions are spatially localised, they can be individually detected and allow for investigating local properties of a cold atomic sample [2]. In order to combine laser cooled ions and atoms in a single experimental setup, we have designed and fabricated a hybrid atom-ion trap based on modern chip trap technology [3]. Here, we report trapping of Yb+ in this device. We plan loading 87Rb atoms into mirror-MOT [4], eventually a magnetic chip trap. We report applications for studies of cold chemistry, cold collisions, and polaron physics.
